The No Doubt singer and clothing designer will donate $1 million to Save the Children's Japan Earthquake-Tsunami Children in Emergency Fund, according to Us Magazine.

In a statement, Stefani said:

"I've been inspired by Japan for many years and have a true love, appreciation and respect for the Japanese people and their culture."

"The disaster in Japan is beyond heartbreaking," she continues. "And I want to do anything I can to help. I would never be able to make a gesture like this without the love and support of all the fans over all these years."

Stefani is also using her L.A.M.B. clothing label to further her efforts. She will be unveiling a limited edition "Harajuku Lovers" T-shirt available for purchase through the official No Doubt web site starting next week. All proceeds from sales of the shirts will go towards relief efforts.
